Thanks, I just made a donation
Thanks a lot.

Also, just to know: how does this software works exactly ? It doesn't change real screen brightness right ?
All it does is create a black GUI window the size of your entire desktop. The GUI is set to always on top, disabled, and click-through. Then, it makes that black GUI transparent to the level you choose. This is what creates the "dimming" effect. You're actually clicking
through a transparent window. Make sense?
Is there any risk of screen calibration modification ? Or damage ?
It doesn't change or mess with your monitor calibration at all.
